Ramchandra Apte added the comment: In http://docs.python.org/dev/tutorial/introduction.html, there is an ... line which is impossible in that case: Variables must be “defined” (assigned a value) before they can be used, or an error will occur:
# try to access an undefined variable
... n Traceback (most recent call last): File "<stdin>", line 1, in <module> NameError: name 'n' is not defined
It should be:
n # try to access an undefined variable Traceback (most recent call last): File "<stdin>", line 1, in <module> NameError: name 'n' is not defined
